Platypus Drink Tube Insulator

Protect your drinking tube from freezing in the winter and excessive heat in the summer with this drinking tube insulation. The new design has a fully concealed bite valve (protects against dirt and frost), a reverse coil zipper with polyurethane coating (prevents the accumulation of ice and snow), a large sliding handle (can be easily opened with one hand – even with a glove) and a Velcro strap for attachment to the shoulder strap (or hydration pack). Suitable for all drinking tubes and bite valves of the series Platypus®.
